No matter where the negative sign is, the product will always be negative, so is the number itself.

13.2(-8.1)=-106.92

twice of that would be -213.84.

first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).

What is the value of x in the diagram below?

VARVARA [1.3K]

Answer:

option B is the right option.

Step-by-step explanation:

<h3>Using leg rule</h3>

$\frac{bc}{ab} = \frac{ab}{bd}$

Plug the values:

$\frac{20}{12} = \frac{12}{x}$

Apply cross product property

$20 \times x = 12 \times 12$

Calculate the product

$20x = 144$

divide both sides of the equation by 20

$\frac{20x}{20} = \frac{144}{20}$

Calculate:

$x = 7.2$

hope this helps..

Good luck...

3x+1/5y=7 solve for y

Vladimir79 [104]

Hello!

First, let's write the problem.
$3x+\frac{1}{5}y=7$
Subtract 3x from both sides.
$3x+\frac{1}{5}y-3x=7-3x$
$\frac{1}{5}y=7-3x$
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
$5\cdot \frac{1}{5}y=5\cdot \:7-5\cdot \:3x$

Our final answer would be,
$y=35-15x$

Thanks!
